The main contributions to the increase in revenue requirement in 00 are: 0 0 Growth of almost $00 million in the installed asset base since rates were established in the year 000. This expansion was required to meet load growth requirements, expand interconnection capability to enable export and import of electrical energy, connect new generators, re-configure the system to accommodate a new supply mix and improve customer delivery point reliability, replace end of life facilities and improve productivity. Increases in OM&A requirements, largely precipitated by increased need for preventative and corrective maintenance associated with an aging fleet of delivery assets, along with an increase in regulatory and industry compliance requirements and the effects of escalation in labour rates, replacement parts and materials. Increases to the Hydro One Transmission Business common equity component and the associated ROE from the current level of.% to 0.0%, based on: the importance of maintaining continued access to long-term debt at reasonable rates, the need to counteract increasing risk factors placing downward pressure on credit ratings, such as uncertainties surrounding timing, completion and ability to recover required new investments and the need to maintain a risk-return profile which is consistent with that of comparable utilities on a global basis, allowing the Company to respond to increasing competition for long-term debt within Canada.
